Systems and methods of transmitting and displaying private message data via a text input application

ABSTRACT

The present disclosure relates to systems and methods for transmitting and displaying private messages securely using a mobile device. The mobile device provides a user interface which is displayed on a mobile device while a messaging application is displayed on the mobile device&#39;s display. A private messaging applet runs within the keyboard region of a mobile device display, and receives and displays private messages from within the keyboard region of the mobile device display. The private message is displayed by initially obfuscating the entire message, and, based on detecting a user&#39;s contact with the display, displaying a smaller portion of the private message in relation to the location of the user&#39;s contact with the display. The private message is automatically deleted from the mobile device after the user removes contact with the display. The private messaging applet allows a user to remove a sent private message from a private messaging server.

REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. patent application Ser. No. 15/399,379, filed on Jan. 5, 2017, which claims the benefit of and priority to U.S. Provisional Patent Application No. 62/418,277, filed on Nov. 6, 2016 and U.S. Provisional Patent Application No. 62/275,125, filed on Jan. 5, 2016. The entire contents of each of the foregoing applications are hereby incorporated herein by reference.

TECHNICAL FIELD

The present disclosure generally relates to private messaging; more particularly, to systems and methods by which computing apparatuses compile, communicate, and display private message data within a virtualized keyboard of a messaging application.

BACKGROUND

Early implementation of data transfer between personal devices was initially limited to less than ten characters per character set. As personal device technology has advanced, messaging applications were developed to address user demand to send communications to additional users without entering into in-person conversations. Traditionally, these messages were transferred between parties, without being secured or encrypted in any fashion, due to computing constraints associated with devices as they originated and terminated the messages.

To facilitate interoperability between various service providers, protocols were developed, such as the Short Message Service (SMS) standard, and subsequently the Multimedia Messaging Service (MMS) standard. These protocols permitted transmission of finite character sets (for SMS) as well as small predefined multimedia files such as audio, video, and longer character sets than are supported by SMS.

More recent techniques allow for the digital renditions of the data prior to being output to a display or other device component to be secured and kept private. Delivery of message data either via SMS or MMS, however, generally requires displaying the transmitted message content on the display of a device. Such display methods may not adequately address the privacy concerns of individuals who prefer to keep the content of their conversations private while in the vicinity of other individuals.

SUMMARY

DETAILED DESCRIPTION

The present disclosure relates to systems and methods for facilitating private communications in an evolving digital age. One common example of private communication today is communication via the transmission and reception of finite sets of characters, e.g., “text messages,” as well as images, audio, and video messages. The transmission of these messages allow for quick correspondence between individuals, often from mobile devices. To address concerns related to user security, and to prevent the loss of confidentiality, device and peripheral manufacturers have developed many obfuscation techniques, such as application of 3M™ privacy screen protectors.

The present disclosure features methods by which messages can be transferred in a secure fashion from a device's components to the user, allowing for greater control over content delivery. Such delivery components generally include digital displays and touch-sensitive displays. For mobile devices, particularly mobile devices with touch-sensitive displays, the methods of the present disclosure permit users to transmit message data securely in crowded areas, or areas where security can be easily compromised. As a result of introducing methods which allow for faster and more selective communications where sensitive data is being transmitted via traditional messaging systems, individuals are able to review messages they would otherwise wait to review in private.

Consider the following messaging example in which a user desires a method by which they can deliver a message privately and securely. In accordance with various embodiments, the user (i.e., sender) using a computing apparatus executes a messaging application on the device. The messaging application may be a generic messaging application which is supported by a carrier associated with the particular communication apparatus. After determining that the data to be transmitted is not generic, but rather is private, the user executes an applet, or thin application, within the messaging application for the purpose of sending a message which can be viewed in a more private or discrete manner.

In response to executing the private messaging applet, the private messaging applet displays a messaging keyboard which functions similarly to that of the messaging application, accepting input from the device's user from a keyboard or other input peripheral. However, unlike the carrier's messaging application, the private messaging applet adds an additional tag to the outgoing message and transmits the message, along with the tag, as a private message data package to a private message server.

Transmission to a private message server permits increased control over the delivery of the private message data, particularly, the ability to recall the message prior to the recipient's opening of the message. Given that the message is stored on a server until the message is transmitted to a recipient communication apparatus, the server can delete the message upon request. Or, if the message has been transmitted to the recipient device, the server can send a message to the recipient device to delete the message. This operation can occur at any point after the transmission of the initial message to the private message server up until any point prior to display of the message on the screen of the recipient device.

Should the transmitting device not send a signal to delete the private message data, the private message data is, if not already, transmitted to the recipient communication apparatus. Once the recipient inputs a request into the recipient communication apparatus to open the message for viewing, a private message screen is displayed, with the sender's message obfuscated as it is displayed.

The recipient's communication apparatus then continuously queries the touch-sensitive display to identify the location of user input, namely, where a finger is touching or in tangible communication with the device display. Upon assessing the location of the user input, and verifying that this input has been continuous and within the region in which the message is to be displayed, a smaller corresponding portion of the message is displayed in the corresponding region in the obfuscated region.

This process of querying the display for continuous location information of user input continues until the user removes his finger from the touch-sensitive display. In an alternative embodiment, the process continues until the user's finger leaves the predefined region in which the message is displayed. As a result, the full image is obfuscated, or alternatively the device removes the private message screen and displays, still within the messenger's keyboard region, the private messaging applet's keyboard. Hence, the user who transmitted the message is able to ensure that, to the extent the recipient is willing to mitigate the chances that their message will be received by an unintended individual, the likelihood of maintaining privacy during the communication is improved over conventional methods of communication currently available.

Although the following description uses terms “first,” “second,” etc. to describe various elements, those elements should not be limited by the use of those terms. Those terms are only used to distinguish one element from another. For example, a first private message could be termed a second private message, and, similarly, a second private message could be termed a first private message. Defining either message as either a first private message or second private message can be defined without departing from the scope of the various described embodiments. The first private message and the second private message are both private messages, though they exist as independent messages.

The terms “connected” or “in communication with” and related terms are used in an operational sense and are not to be limited to a direct physical connection. For example, two devices may be coupled together via a wireless network or via a physical connection. Based on the disclosure provided herein, a person of ordinary skill in the art will appreciate a variety of ways in which devices can be connected or in communication with one another, in accordance with the aforementioned definition.

FIGS. 1A and 1B provide a description of exemplary devices connected for performing the functions of accepting, tagging, transmitting, and selectively displaying private message data containing private messages.

Network 100 can include any combination of local area networks (LANs), wide area networks (WANs), wireless local area networks (WLANs), Metropolitan Area Network (MAN), wireless networks, secured networks such as virtual private networks (VPNs) or any other suitable system of interconnected devices in which data packets are transferred between two or more devices via connections 102. In one embodiment, network 100 uses standard communications technologies and/or protocols to establish connections 102 in order to facilitate the transfer of data packets between a plurality of independent devices. As a result, network 100 may be capable of transmitting a variety of data of a variety of data formats for increased interoperability between devices across a variety of connections 102. The use of technologies, including but not limited to, Ethernet, 802.11 (a/b/g/n/ac), 3G, 4G, CDMA, digital subscriber line (DSL), and the like, permits the communication between a variety of devices which may be configured to transmit and receive data in varying protocols. Further, implementation of certain protocols facilitates the transfer of data across network 100 such as transmission control protocol/internet protocol (TCP/IP) or hypertext transport protocol (HTTP), simple mail transfer protocol (SMTP) and file transfer protocol (FTP) allow for more uniform and efficient transfer of data between varying devices along network 100.

Public messaging server 140 can be any computing device configured to store, process and transmit message data. Such services today are traditionally being hosted by an existing internet service provider (ISP) or mobile service provider (mobile carrier), but also by third party corporations such as Google®, Apple®, Facebook®, WhatsApp®, or Snap Inc.®, which host private messaging utilities such as Google Hangouts® or iChat®. Public messaging servers 140 can accept a variety of either publically available or proprietary file formats.

Device 110 can be any computing apparatus which is capable of both accepting input, either through a touch-sensitive screen, peripheral (such as a keyboard), audio streams, video streams, or data from other sensors embedded or communication with the computing apparatus. Device 110 can be calibrated to engage with public messaging server 140 to optimize message transfer and interoperability, as well as with public messaging servers 140. Public messaging servers 140 can enhance interoperability by interacting with corresponding messaging applications or by implementing standards which are accepted by the service provider community, such as SMS or MMS messaging.

Device A 110 and Devices 130 a-130 n can be electronic devices which are capable of executing computing functions, examples of such devices including mobile phones, desktop computers, thin client computing devices, laptop computers, virtualized computers, cluster or cloud computing environments, application specific integrated circuits, field programmable gate arrays, or any combination thereof.

Connections 102 can include a variety of connection techniques such as interconnection of digital devices via wireless communication on the 802.11 standard (a/b/g/n/ac) (wifi), Ethernet, 3G, 4G, CDMA, digital subscriber line (DSL), and the like. Further, data transmission over a connection 102 may be accomplished with TCIP/IP, HTTP, secure hypertext transfer protocol (HTTPS), SMTP, and FTP may all be implemented in transferring data across connections 102.

User 150, 150 a-150 n can be any means of generating device 110, 130 a-130 n input, such input generally being received by a person or persons. Other means of input by a user 150 can be by simulation such as Apple®'s Siri®, or Microsoft®'s Cortana®.

Private messages 112 a-112 n, can be any object stored in data which is translatable, either by hardware or software implemented methods, and recognizable by a device 110.

In accordance with some embodiments, private messages 112 a-112 n may be transferred via a connection 102 to a private message server 120 via a network 100. The private message can include any encoding of a translatable set of data, ranging from Arabic letters (commonly referred to as characters), arrays of characters (strings), images, compressed images such as those compressed under the Joint Photographic Experts Group (JPEG) standard, video, compressed video such as Moving Picture Experts Group Phase 1 (MPEG-1 or MPEG), or other proprietary data sets.

The private message also includes a tag or other similar identifier that identifies the message as a private message. The tag and private message 112 a-112 n may be transferred together as a private message data packet. The private message data can then be stored on a private messaging server 120 which is configured to receive and store data from a variety of devices 110, 130 a-130 n. Private messaging servers 120 can be configured to store the data either as it is transmitted or in a converted manner for data storage optimization. Such private message data, once received by a private messaging server 120 can then be stored in server memory with a mailbox 122 a-122 n tag, the mailbox tag designating both the source and destination of the data stored on the private messaging server 120.

FIG. 1A illustrates an example of a high level network environment, the network environment depicting the connections 102 between multiple computing apparatuses, including devices 110, 130 a-130 n, as well as a private messaging server 120 and public messaging server 140. The described devices 110, 130 a-130 n, public messaging server 140 and private messaging server 120 are all interconnected via a network 100, the network facilitating data transactions between computing apparatuses along data paths 104 a-104 n.

FIG. 1B illustrates the transmission of a private message 112 a-112 n to a variety of recipients via a private messaging server 120. Device A 110 engages in a series of data transactions along data paths 104 a-104 n which translate, and verify the translation of, data between transmission devices based on predetermined transmission protocols such as Device A 110 and a recipient device or devices such as a private messaging server 120 and ultimately Device B 130 a and Device C 130 b. The initial data transaction transmits private message data, including a private message 112 a-112 n, as well as a tag if the message is marked private, and any intended recipient data, such as identifying address for User B 150 b and/or User C 150 c.

As stated, private messaging servers 120 can be configured to optimally tag, store, and ultimately transmit private message data, including private messages 112 a-112 n.

The embodiment depicted in FIG. 1B includes mailboxes 122 a-122 n stored within the memory of a private messaging server 120, which include demarcated regions in memory allocated to device 110, 130 a-130 n. Mailboxes 122 a-122 n can contain additional tags associated with the private message data stored in the mailbox 122 a-122 n, such additional tags including device 130 a-130 n address information, device 110 address information, and locks to prevent transfer of the data to a recipient.

FIG. 2 illustrates a set of components within a device 110, 130 a-130 n according to one or more embodiments of the technology disclosed herein. According to the embodiment disclosed in FIG. 2, device 110, 130 a-130 n can include memory 202, a memory controller 204, non-volatile memory 206, page tables 208, one or more processors, including main processor 210, component interfaces 250, input/output (I/O) component controllers 220, external signal processors 216 a and device components 222 a-222 e. Other embodiments of the disclosed technology may include some, all, or none of these elements along with additional or different modules, applications, and/or components. Likewise, some embodiments may incorporate two or more of these modules and components into singular modules or components. Alternatively, some embodiments may implement the functionality of the disclosed embodiments in different manners, such as by combining, reorganizing, or substituting components or modules. For example, Application 1 202 f may not contain Applet memory within the memory space allocated to Application 1, with the memory space located alternatively in a unique region within global memory 202 p space. Such memory may be allocated at runtime, or may be allocated upon Application 202 f execution.

It will be recognized by one skilled in the art that the device 110 shares many of the same components and configurations with both the private messaging server 120 and public messaging server 140. One skilled in the art will also recognize that, depending on the amount of devices connecting to either the private messaging server 120 or public messaging server 140, different configurations will be desirable for increasing message handling efficiency. Such configurations may include the virtualization of such devices within hosted environments such as Microsoft®'s Azure® environment, Amazon®'s Web Services® (AWS®) or Google®'s Cloud Platform Service™.

Memory 202 can be any device, physical structure, and/or populated data structure which functions as a recorded media storage device. In some embodiments, memory 202 may be computer memory which is volatile, or rather, memory 202 which does not maintain its state once an electric current is no longer available. Memory 202, which in some embodiments is volatile, may be substituted in alternative embodiments with non-volatile memory components, dynamic memory, or redundant memory. Examples of such memory 202 include random access memory (RAM), memory storage devices, optical memory devices, medial magnetic media, floppy disks, magnetic tapes, disc hard drives, solid state hard drives, SDRAM, DDR RAM, erasable programmable read-only memories (EEPROMs), compact discs, DVDs, or other methods of storing data in a medium for future retrieval or modification. In accordance with some embodiments, memory 202 can be contained within one contiguous region of a physical device, may span across multiple regions on a physical device, or may span multiple memory 202 devices such as virtual memory allocated within traditionally non-volatile memory 206 space.

Operating system 202 a can provide a device environment which permits the continuous initialization, execution, storage, and termination of one or more applications 202 f-202 n. Operating systems 202 a are generally stored in non-volatile memory 206 and are initialized when power 214 is applied to a device, such power being regulated by a regulator 212. The operating system 202 a, once initialized, controls the generation of applications 202 f-202 n, and allocation of resources to applications such as an initial address space within memory 202, cycles to execute functions on the main processor 210 and access to non-volatile memory 206 such as pages 206 a-206 n stored in virtual memory, according to one disclosed embodiment.

Page table 208 can be any device which accurately maps the data locations stored within memory 202 and non-volatile memory 206, sometimes referred to as pages 206 a-206 n. In some embodiments, page tables accurately store and retrieve data, swapping information between memory and non-volatile memory 202, 206 regions between device components. Page tables 208 facilitate the transfer of pages 206 a-206 n, which in turn allow for the storage of application-specific data for use after the application has terminated or has been forced from memory 202.

Non-volatile memory as stated earlier, can be any type of memory which permits extended temporal storage of media. In some embodiments, non-volatile memory can be a solid state hard drive (SSD), disk drive, tape drive, compact disc, or virtual memory which is either stored local, or remote from the device. One skilled in the art will appreciate additional devices, storage techniques, and device configurations which can simulate or act as functional equivalents to existing disclosed device memory configurations.

Device applications, and in particular public and private messaging applications, can be stored in memory 202 and retrieved for later execution on a device 110, 130 a-130 n. In certain embodiments, main processor 210 can execute various applications and sub-applications or “applets” which include instruction sets stored in memory 202. In some embodiments, processors may be included in certain device components such as I/O components. For example, one skilled in the art will appreciate that a device display 220 a may contain within the component's hardware a processor for executing certain graphical functions separate from the application's execution on the device's 110 main processor 210.

A component controller 220 can be any device module or component which handles the transmission of I/O data collected from device components 222 a-222 e, such as cameras 222 b, device displays 222 a, device buttons 222 c, microphones 222 d, and speakers 222 e. Device displays 222 a can be either traditional displays or touch-sensitive displays. In some embodiments, where a touch-sensitive display 222 a is implemented, the component controller 220 controls both the output of display information to either a display processor or directly to the display 222 a, as well as the input from the touch sensitive display 222 a simultaneously, and transmits the input data in relation to the output data to a display module 202 e for use by applications executed by the main processor 210.

Component interface 250 can be any signal processor which implements a routing system between a variety of sub-components and controllers. In some embodiments, a component interface 250 routes signals accepted from both a component controller 220 and a transceiver 216, the transceiver 216 handling the transmission and receipt of externals with an external signal processor 216 a.

The private message jump bar can include one or more private message icons 318, the private message icons indicating whether a private message, stack of private messages, or array of private messages are available on the device 110 for review.

FIG. 3D depicts a device which, upon display of a set of private message icons 318, executes the display function on one of the private message icons 318, and displays an obfuscated message on a display 222 a. In certain embodiments, the private messaging applet region contains a private message region 322 which displays an obfuscated version of the private message. In some embodiments, the obfuscated version of the private message correlates to an unobfuscated version of the private message which is partially displayed once the user selects a portion of the obfuscated version of the private message. In other embodiments, the private message may be obfuscated by applying an obfuscating or blurring filter to the private message. Then, when a user selects a portion of or a region within the obfuscated private message, the private messaging applet removes the obfuscating filter from only that portion or region of the private message selected by the user.

FIG. 3E depicts an embodiment of the device as displayed in FIG. 3C. In the displayed embodiment, the obfuscated private message content is displayed within the private message region 322, the private message bounded by the private messaging applet region 314. A portion of the private message is selected by the user 150 a-150 n and a corresponding portion of the private message is displayed unobfuscated in accordance with the location selected.

The private messaging applet displayed contains within it a private message input region 404, a private messaging applet region 314, a private message jump bar button 312, and private message send button 310. The private message jump bar button 312 is configured to execute instructions upon selection to swap out the private message input field 308 with the private message jump bar 316, and vice versa.

FIG. 5B depicts the display of FIG. 5A once the private message jump bar button 312 has been selected. As a result of the private message jump bar button 312 actuation, the private message applet region 314 of the display includes a private message jump bar 316 in lieu of a private message input field 308 and private message send button 310. Actuation of the private message jump bar button 312 returns the private message applet region 314 to its initial state depicted in FIG. 5A.

FIG. 5C depicts the display of FIG. 5B after the private message jump bar button 312 has been selected a second time. The device 110 displays the private messaging applet region in an initial start state as depicted in FIG. 5A, however, the private message input field 308 no longer containing a text input within the private message input region 404.

FIG. 6A is an example of a messaging application in a default state, the messaging application including a messaging application keyboard region 304, a message input field 320, and a private messaging applet button 300. The private messaging applet button 300 as embodied in FIG. 6A is displayed as a pull down bar 600 which in one state does not relay any notification information.

FIG. 6B is an example of a messaging application in a second state, the messaging application including a messaging application keyboard region 304, a message input field 320, and a private messaging applet button 300. The private messaging applet button 300 as embodied in FIG. 6B is displayed as a pull down bar 600 which in one state relays notification information. The pull down bar 600 as embodied in FIG. 6B displays on the display 222 a that two messages are currently awaiting review.

FIG. 7A is an example of a user interface which includes a private message applet button 300 which is displayed in the form of a pull down bar 700. As embodied in FIG. 7A, the pull down bar 700 contains an indicator as to which state the private messaging applet is in. The private message input field 308 is included in the private messaging applet region 314 of the display 222 a.

FIG. 7B is the interface of FIG. 7A, with the pull down bar 702 displaying information relating to the second state of the device 110. In the second state, a private message jump bar 316 is displayed along with a series of private message icons 318 in place of the private message input field 308.

FIG. 8A is an example of an interface which includes a private message jump bar button 312. The private message jump bar button 312 is attached to a private message applet region 314 which includes recently messaged contact icons 800 and a list of existing contacts. The list includes inviteable contacts 804 which can be sent an invitation to install the private messaging application upon selection of the inviteable contact 804.

FIG. 8B is an example of an interface which includes a private message recipient indicator 802 which indicates that the input message is to be sent to two devices 110. FIG. 9A is an example of an interface which contains, within the private messaging applet region 314, a private messaging inbox 902, which populates a list of existing messages stored either on the devices 110 or on the private messaging server 120.

FIG. 9B is an example of an interface which contains, within the private messaging applet region 314, a private messaging outbox 900, the private message outbox having a list containing outgoing messages 908, with each outgoing message having a recall button 906 which, when selected, sends a recall notice to the private message server 120, which, in turn, marks and deletes the private message as well as transmits a signal to the recipient device or devices 110 to delete the message if it is still in the private messaging applet's inbox.

FIG. 9C is an example of an interface displaying a screen after a sent message has been selected for recall. The sent message screen 910 includes a cancel button 912, which, when selected, disregards the user's initial request to recall the sent message. The sent message screen 910 also includes a recall button 914, which, when selected, sends a signal to the private messaging server 120 to recall the message. In turn, the private messaging server 120 sends a message to recipient devices 110 to delete the message. In embodiments, the private messaging server 120 sends a message to recipient devices 110 to delete the message if the message is not already displayed on the recipient devices 110.

FIGS. 10A-10C is an example interface illustrating an embodiment in which selection of the private messaging button 306 by a user causes the private messaging applet region 314 to appear. In embodiments, a user 150, 150 a-150 c selects or presses the private messaging button 306 by selecting the location of the private messaging button 306 on the touch-sensitive display 222 a, and, while maintaining contact with the initial location on the touch-sensitive display 222 a, translating or swiping the input, e.g., a finger or pointing device such as a stylus, in a downward direction toward the bottom of the messaging application keyboard region 304 to reveal the private messaging applet region 314. Once this translation or swipe has revealed the private messaging applet region 314, a private message jump bar button 312 is displayed, which permits a user 150, 150 a-150 n to switch between private messaging applet states as described in the embodiment of FIGS. 7A and 7B.

FIG. 11 is a flow diagram illustrating initial actuation of the private messaging applet, and transmission of a private message. In one embodiment, the device 110 receives user input at block 1100 from a touch-sensitive display. The device 110 then determines whether the input at block 1100 was within a predetermined region on the display 222 a. If it is determined that the user 150, 150 a-150 n input was within the predefined region on the touch-sensitive display corresponding to the private messaging button 306, the messaging application causes the private messaging application to be executed at block 1120 on the device 110.

Upon execution, the private messaging applet displays a default display, which is contained within the private messaging applet region 314 of the keyboard. Simultaneously, the private messaging applet prepares a private message data packet to be sent to a recipient, which initially is the predefined default recipient at block 1120.

After initializing the initial private message data with the predefined default recipient at block 1120 the private messaging applet then determines whether a different recipient has been selected at block 1130, other than the default recipient, and if a different recipient has been selected, sets the recipient of the private message data to the address of the selected recipient at block 1140.

After determining the proper recipient, the private messaging applet receives input text at block 1150 from the display 222 a. While the applet is receiving input text at block 1150, the state of the display is reevaluated at block 1160 to determine whether the next user input is selection of the private message send button 310. Upon detecting a user input which is determined to be a selection of the private message send button 310 at block 1160, the private messaging applet causes the private message data to be transmitted to the private message server 120. The private message data may include a tag indicating that the private message is private and address data identifying the recipient.

FIG. 12 is a flow diagram illustrating a process associated with displaying a message in the private messaging applet region 314 on the display 222 a. In one embodiment, a device 110 receives a request to display a private message at block 1210 from a user 150, 150 a-150 n. The device 110 is then checked by the private messaging applet to determine whether the private message selected for display at block 1210 is stored locally on the device 110, either in memory 202 or in non-volatile memory 206. If the private message is determined not to be stored on the device 110, the applet causes the device 110 to retrieve the message at block 1230 from the private messaging server 120, and store the private message in memory 202 prior to being displayed.

Once the private message is stored on the device, the private messaging applet detects user 150, 150 a-150 n input on the touch-sensitive display 220 a continuously at block 1240 until user input is determined to be within the private messaging applet region 314 of the touch-sensitive display at block 1250. After the user input is determined to be within the private messaging applet region 314 of the display, e.g., after a user's finger makes contact with the private messaging applet region 314 of the display, the private messaging applet causes the display 222 a to display an obfuscated private message within the private messaging applet region 314. For example, each of the characters of text in a private message may be shown as a dot or another character different from each of the characters of text in the private message. As another example, text and/or images in the private message may be blurred or distorted so as to be illegible or unreadable.

The private messaging applet also causes a portion of the private message to be displayed without being obfuscated at or near the location at which the user input was detected at block 1260. The private messaging applet then retrieves the next user input at block 1270, e.g., the user's finger, while continuing to make contact with the touch-sensitive display, moves to another location on the touch-sensitive display. If the next user input at block 1270 is determined to be located within the private messaging applet region at block 1280, a portion of the private message at a location at or near the location at which the user input was detected at block 1260 is displayed without be obfuscated.

When the private messaging applet determines that the user input is no longer located within the private messaging applet region 314 of the display at block 1280, e.g., when the user's finger or a pointing device no longer makes contact with the private messaging applet region 314 of the display, the private messaging applet causes the device 110 to stop displaying the private message at block 1290 within the private messaging applet region 314 of the display 222 a. In embodiments, the private messaging applet causes the device 110 to stop displaying the private message after a predetermined period, e.g., 500 ms or 1 sec, has elapsed. The private messaging applet then causes the device 110 to delete the private message data from memory at block 1292.

FIG. 13 is a flow diagram illustrating a process of displaying a portion of the private message corresponding to the user input. In one embodiment, a device, e.g., one of devices 110, retrieves the determined region bounds for a private message applet region 314 on a touch-sensitive display 222 a at block 1310. Once the region bounds are determined at block 1310, the private messaging applet displays an obfuscated image, e.g., a default obfuscated image indicated by settings for the private messaging applet, at block 1320 within the private messaging applet region 314 of the display 222 a. While displaying the obfuscated image at block 1320, the private messaging applet determines the location of user input, e.g., a user's finger or a pointing device, on the touch-sensitive display at block 1330 and, based on the location, determines whether the user input is located within the private message applet region 314 of the display at block 1335. If the user input is not located within the private message applet region 314 of the display, the private message applet determines the location of the next input at block 1330 and whether the user input is located within the private messaging applet region 314 of the display at block 1335 until the user input is determined to be within the private messaging applet region 314 of the display.

After the determination is made that user input is located within the private messaging applet region 314 of the display, the private messaging applet displays only that portion of the private message data within a sub-region of the private messaging applet region 314 of the display corresponding to the user's input at block 1340.

The private messaging applet then determines if a next input location has been detected at block 1345 and, if so, the private messaging applet retrieves the input location data at block 1350. The private messaging applet also determines whether the input location is still within the private message region 322 of the display, and, if so, displays only that portion of the private message data that correlates or corresponds to the location on the display where the input was determined to be located at block 1340. If there is no next input location detected, for example, for a predetermined period, the private messaging applet causes the device to delete the private message data at block 1360. Likewise, if the next input location is determined not to be in the private message applet region 314 of the display, the private message data is deleted at block 1360.

FIG. 14 is a flow diagram illustrating the process of recalling a message, and, if no recall is requested, transmitting the message, upon user request, to device 110 to be displayed. In some embodiments, device 110 receives private message data at block 1400 and stores the private message data at block 1410 on a private messaging server 120. After storing the private message data at block 1410, the private messaging server 120 determines whether the message has been recalled by the device 110 at block 1420. If the device 110 has sent a request to the private messaging server to recall the private message data, the private message server deletes the private message data at block 1430.

If the private messaging server 120 does not receive a request to recall the private message data, the private messaging server 120 determines whether the recipient or recipients have requested the message at block 1440. Where the recipient or recipients have not requested the message, the private message server returns to the earlier recall check state at block 1420 and determines whether the message has been recalled.

Where it is determined that a recipient has requested the message at block 1440, the private message server 120 transmits the private message data to the intended recipient or recipients at block 1450. After transmission, the private message data is displayed at block 1460 on the recipient device 110, after which the private message data is deleted from the device at block 1470.

In some embodiments, the user 150, 150 a-150 n can input text-based messages, which is shown in FIG. 4D. Other types of data to be transferred based on this private messaging technique will be apparent to those of ordinary skill in the art. Likewise, storage of other non-text based media within a private messaging server 120 and transmission of such media to recipient devices 130 a-130 n will also be apparent to those of ordinary skill in the art who practice this invention.

The disclosed technology provides novel systems, methods, and arrangements for the transmission of message data between devices and secure display of the message to a user in a space where privacy is limited. Though detailed descriptions of one or more embodiments of the disclosed technology have been detailed above, various alternatives, modifications, and equivalents will be apparent to those of ordinary skill in the art without varying or departing from the spirit of the invention. For example, while the embodiments described above refer to particular features, components, or combinations thereof, such features, components, and combinations may be substituted with functionally equivalent substitutes which may or may not contain the elements as originally described or arranged.
